You can find a yellow light known as the "TCS light" on the dashboard, which comes on at times. So, what does the light tell us?
1) The TCS light flashes as soon as your car starts accelerating.
The TCS light blinking upon acceleration could mean that the surface is not offering much friction. The light is designed to flash when driving on a snowy, muddy, or icy road. However, if the light blinks while your car slows down and the road is not slippery, then the issue could be with the ABS (Anti-lock braking system) sensor on your vehicle. In this case, check the codes from the ABS control unit to see if the sensor is failing to function.
2) The TCS light is on with an OFF sign underneath.
Simply, this means that your TCS is off. You can easily turn the TCS system on and off with a button inside your car. If you cannot find the button, look at the service manual to find out where it is.
3) The TCS light is constantly on.
A continuous TCS light, often accompanied by the ABS light, means something is going on in your traction control system. The solution is to read the codes in the ABS control unit and see what they say. Also, you can have your mechanic take a look.
